WALTER C. BRADFORD, OF GERMANTO WN, CALIFORNIA.

TWO- WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 329,132, dated October 27, 1885. Application filed August 26, 1885. Serial No.175,373. (No model.)

To all whom it may concern.-

' Be it known that I, WALTER O. BRADFORD, of Germantown, in the county of Oolusa and State of California, have invented a new and Improved Cart, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved cart of a special construction which is strong and durable, and rides very easily.

The invention consists in the construction and combination of parts and details as will be fully set forth and described hereinafter, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved cart, parts being in section. Fig. 2 is a plan view of the under side of the same. Fig. 3 is a detail longitudinal view of the adjustinggear. Fig. 4 is a detail side view of the front adjusting-gear. Fig. 5 is a plan viewof the same. Fig. 6 is a side view of the connectingbars of the front gear.

On the under side of the vehicle-body A a frame, B, is secured at each side and some distance behind the axle, which frames B each have bottom bars, rests loosely.

On each end of the shaft 0 a cog-wheel, D, is mounted, which engages with a rack, E, formed on the bottom edge of the top piece of the frame B. On one end of the shaft 0a handle-bar, F, is secured, on which a sliding locking-bolt, G, is provided, the end of said bolt being adapted to be passed in the notches formed between the teeth of a curved rack, H, on the frame B, or racks J on the ends of said frame.

The steel springs K each have one end passed around the shaft 0 loosely in such a manner that the shaft can turn in the eyes thus formed on the end of the springs. The springs are coiled in the manner shown, and their other ends are clamped by plates on castings M, on which the shafts N are held by bolts. The

B, on which a shaft, 0,

castings M are clamped on the axle O. Arms P, formed on the castings M, project toward and carry rubber cushions Q on their supporting and holding the body in the rear, ends for case the weight on the same swings it down too far.

Straps B connect the ends of the arms I? and the frames B. The front spring, S, is secured to the under side of the body, and at its front end it is secured in a roller, T, held at its end in rings on the ends of the shanks of a forked piece, U, held by jointed rods S on the bar WV, uniting the shafts N.

The roller T has notches a in its end pieces and into said notches a key, 12, in the forked pieces U can pass, which key is connected with a spring, d, in the forked piece, and is provided with a handleknob, g.

The operation is as follows: the handle-bar F in the direction of the arrow a the wheels D are turned in the direction of the arrow 1), and the box or body A is moved to the rear, and thus more weight is thrown in the direction desired, whereby the horse can be relieved. WVhen less weight is desired, the handle F is moved in the inverse direction of the arrow a, whereby the body is moved to the front, and the springs are uncoiled. The bar F can be lockedin any desired position by the bolt G, and thus locks the springs at the desired tension. To adjust the front spring, the key b is with drawn, and the front of the body is raised more or less, the roller T turning in the rings on the end of the shanks of the forked piece U, and when the body has been adjusted the key I) is pushed in place to lock the roller T. For example, when the roller has been turned in the direction of the arrow at by raising the body and has been locked in place the body is kept raised, as the roller cannot revolve, and the spring S can only coil or uncoil when the roller is loose to revolve. In a similar manner, but inversely, the body is adjusted when lowered to prevent the spring S from raising it.

The straps R prevent the body from j umping too much, but may be omitted, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A cart having the supporting-springs each held at one end on the axle and at the other end on a rod mounted movably on the box or body, substantially as herein shown and described.

By swinging 2. A cart having the supporting-springs each held at one end on the axle and at the opposite end on a shaft, provided with gearing for adjusting its position on the body, substantially as herein shown and described.

3. In a cart, the combination, with the body and axle, of springs secured on the axle, a shaft on the wagon-body, to which shaft the upper ends of the springs are secured, cogwheels on the ends of the shaft, racks in which the cog-wheels can run, a handle-lever for turning the shaft, and devices for locking the shaft in place, substantially as herein shown and described.

4. The combination, with the body A and axle O, of the frames B on the body, the racks E, formed in said frames, the shaft 0, passed through the frames, the cog-wheels D, mounted on the shaft and engaging with the racks E, the handle-bar F on the shaft 0, the locking-bolt G on the handle-bar, and the curved vracks H and J on one frame B, substantially as herein shown and described.

5. The combination, with the body A and the axle O, of the springs K, for supporting the body from the axle O, the arms 1?, project.

ing from the axle, and the cushions Q on the said arms, substantially as herein shown and described.

6. The combination, with a wagon-body mounted to rock above an axle, of a spring secured to said body and on a roller held adjustably on the frame of the vehicle, substantially as herein shown and described.

7. The combination, with a wagon-body mounted to rock'above an axle, of a spring secured on the front of the body, a forked piece on the frame of the vehicle, a roller in said forked frame, to which roller the front end of the spring is secured, and a key for locking the roller in place on the forked piece, substantially as herein shown and described.

8. Avehicle having its body hung at the front and rear 011 springs, all the springsh'aving tension-adj usting devices, substantially as herein shown and described.
